I wonder if it is possible to install FSAVCS 13.11 and then upgrade it PARTIALLY to FSCS 14.01, so that only the anti-virus part is upgraded to use new the lean scan engines, but F-Secure's proprietary IS/DFW firewall module remains in use? It would probably need some hacking to achieve such a "hybrid" environment.
